There are two really big organic chemistry RUclips channels with millions of subscribers. They need to be taking notes because your videos are the clearest by far!
I just found your channel couple weeks ago and honestly your explanations are crystal clear , especially since I am having problems with understanding my organic chem lectures. You are heaven sent and I just want to thank you.
Heaven sent, so helpful. Ochem actually makes sense now. Your lessons have amazing structure and organization that makes the material easy to follow and understand.
Love your videos. They are very clear and concise. I am taking organic chemistry right now and whenever a classmate asks me for resources for organic chemistry or general chemistry I recommend them to you. I found you in general chemistry II and you helped me so much. Thank you so much for the videos and for the big effort you put into them.
literally just right now I was like hmmm i’m having trouble in this chapter, let me see if chads prep has anything on youtube. i then come to see you posted this video 5 minutes ago. it’s as if you read my mind chad. 😭
Awesome Mohab! It is advantageous to post these right when they are likely to be watched so I'm trying! But obviously there is a little variation in timing from class to class and school to school and I've also heard that a number of colleges are ending the semester early due to the pandemic so my apologies to any for whom this is posted too late to be of help! Happy studying!🙃
Rather than the product attacking and the rearragement occurs, the intermediate carbocation rearranges to form the more stable carbocation and then the nucleophile attacks
Hi Chad, My orgo professor says that a more substituted alkene would be less reactive towards acid catalyzed hydration than say something like ethene, since ethene is less stable, and thus more reactive. Yet, it forms the least stable carbocation, so wouldn't it be less reactive than something like 1-methylpropene? Thanks.
Hi Austin! Both enantiomers are the result of anti-addition. Keep in mind the anti addition refers to the relationship between the OH added and the H that is added on the terminal carbon. The enantiomer on the left has the OH on a wedged bond so the H would have been added with a dashed bond. The enantiomer on the right has the OH on a dashed bond so the H would have been added with a wedged bond. It is easy to miss on this one because we are not drawing in the H that was added and it is not on a chiral center anyways. But where the OH added is a chiral center in the product. And remember, when you form 1 chiral center in an alkene addition reaction will always form both R and S (and if it is the only chiral center in the entire molecule then it will be a racemic mixture). And it wouldn't matter if it was syn addition, anti addition, or didn't have any stereoselectivity at all. With only 1 chiral center forming, you get both R and S. Hope this helps!
Hi Chad! I'm doing chem at uni so unfortunate not off the hook for learning the last step involving peroxide and base for the hydroboration mech. You mentioned that that part of the mech is on your website, but I can't seem to find it - is it ok if you could link it to me pls? Thanks!!
Chad, you are gifted by God to teach! thank you so much!!
You're welcome and Thank You.

Thank you very much.
100% agree. So much clearer than the others (I’ve tried them all!)
@@rubyraptor Glad the channel is helping you.
i don't know what i would do for ochem without your videos
Glad the videos are helping you!

You're welcome, Kay - glad you found the channel!

That sounds great - Glad you find the channel so useful!

Thanks for saying so and thanks for telling people about the channel - all the best!

it's crazy how some professors don't emphasize teaching specific differences. Super helpful thanks!
You're welcome, Franco!
somehow understood more in a 20 min video than what I did in my entire lecture. tysm 😄😄😄
You're welcome - Glad you found us!
19:37 "I've seen once in 20 years, students be on the hook for this." I love the fact that I am the lucky student to be on the hook for this
You win!
Same.
such an awesome channel, I'm always able to count on your stuff to help me when I need it
Excellent, Tyler - glad to hear it!
Im so glad I found you, your explanations are very clear. Thank you
We are too, c santrich - You're welcome!
This was a great video. Everything was so clear. Preciate you sir 🤝🏽
Glad to hear it!
you're a genius chad
Thank you - Happy Studying!
I love u man ... Pls keep going don't stop ❤️❤️❤️❤️❤️☺️
Thanks for the feedback! Keep up the learning!
fantastic Sir Chad!
Thank you!
and i am on the hook for the second step of hydroboration oxidation 😀
Thank you Chad!!!!!
You're welcome.
20:43 soooo if you don’t have 3 alkenes the product wont work? Highly unlikely but random question
at 22:21, wouldn't some product also be from the secondary carbocation being attacked before rearrangement?
Rather than the product attacking and the rearragement occurs, the intermediate carbocation rearranges to form the more stable carbocation and then the nucleophile attacks
At 4:50, where did the single H at the left side go?

Hello Chad, does H2SO4 cat. mean the same thing as H2SO4 dilute?
23:30 you drew a racemic mixture but it's anti-addition? Shouldn't it just be the left enantiomer?
Hi Austin! Both enantiomers are the result of anti-addition. Keep in mind the anti addition refers to the relationship between the OH added and the H that is added on the terminal carbon. The enantiomer on the left has the OH on a wedged bond so the H would have been added with a dashed bond.

That makes perfect sense. Thank you so much!!!!!!
Hydroboration is anti markovnikov bc it doesn’t want to be borane 😂 like the other hydration mechanisms. 15:06

Not a problem. You'll find it at the bottom of this page: www.chadsprep.com/chads-organic-chemistry-videos/hydration-of-alkenes/ 😊
@@ChadsPrep chad, you are the holy grail of organic chemistry. You deserve everything on your bucket list !!
